Cylindrically Symmetric Inhomogeneous Universes with a Cloud of Strings
Cylindrically symmetric inhomogeneous string cosmological models are
investigated in presence of string fluid as a source of matter. To get the
three types of exact solutions of Einstein's field equations we assume , and . Some physical and geometric
aspects of the models are discussed.Comment: 9 page
A New Class of Inhomogeneous String Cosmological Models in General Relativity
A new class of solutions of Einstein field equations has been investigated
for inhomogeneous cylindrically symmetric space-time with string source. To get
the deterministic solution, it has been assumed that the expansion ()
in the model is proportional to the eigen value of the shear
tensor . Certain physical and geometric properties of the
models are also discussed.Comment: 12 pages, no figure. Submitted to Astrophys. Space Sci. arXiv admin

Kemampuan Serapan Abu Tulang Kambing terhadap Variasi Konsentrasi Ion Sulfat
Calcium oxide was a major component in bone ash. This calcium oxide has relativelyopened structure, so it can be used as an adsorbent. Its adsorption ability on sulfate ionhas been analyzed in an solution. The analysis of sulfate ion was carried out usingSpectrophotometer UV-VIS by turbidimetry method. The results showed thatconcentration of bone ash affected to the adsorption of sulfate ion with optimumadsorption of 80.833% at 10 ppm of bone ash
Bianchi Type V Viscous Fluid Cosmological Models in Presence of Decaying Vacuum Energy
Bianchi type V viscous fluid cosmological model for barotropic fluid
distribution with varying cosmological term is investigated. We have
examined a cosmological scenario proposing a variation law for Hubble parameter
in the background of homogeneous, anisotropic Bianchi type V space-time.
The model isotropizes asymptotically and the presence of shear viscosity
accelerates the isotropization. The model describes a unified expansion history
of the universe indicating initial decelerating expansion and late time
accelerating phase. Cosmological consequences of the model are also discussed.Comment: 10 pages, 3 figure
Covariant baryon charge radii and magnetic moments in a chiral constituent quark model
The charge radii and magnetic moments of all the light and strange baryons
are investigated within the framework of a constituent quark model based on
Goldstone-boson-exchange dynamics. Following the point-form approach to
relativistic quantum mechanics, the calculations are performed in a manifestly
covariant manner. Relativistic (boost) effects have a sizeable influence on the
results. The direct predictions of the constituent quark model are found to
fall remarkably close to the available experimental data.Comment: 6 pages, 4 table
Observing Long Colour Flux Tubes in SU(2) Lattice Gauge Theory
We present results of a high statistics study of the chromo field
distribution between static quarks in SU(2) gauge theory on lattices of volumes
16^4, 32^4, and 48^3*64, with physical extent ranging from 1.3 fm up to 2.7 fm
at beta=2.5, beta=2.635, and beta=2.74. We establish string formation over
physical distances as large as 2 fm. The results are tested against Michael's
sum rules. A detailed investigation of the transverse action and energy flux
tube profiles is provided. As a by-product, we obtain the static lattice
potential in unpreceded accuracy.Comment: 66 pages, 29 figures, uuencoded latex file with epsfigures (450 K),

A PILOT STUDY OF PIPPALYADI TAILA YONIPICHU IN THE MANAGEMENT OF KAPHAJA YONIYVAPAD (NON-SPECIFIC VAGINITIS)
Background: Vaginitis is an inflammatory process involving the vagina, expanding often to the contiguous anatomical structures (cervix and vulva). Non-specific vaginitis is usually caused by an alteration (disruption) of the normal vaginal microflora, usually represented by the presence of Lactobacilli. Nonspecific vaginitis can be correlated to Kaphaja Yonivyapad based on its Lakshanas.
Objectives: To evaluate the efficacy of Pippalyadi taila yoni Pichu in management of Kaphaja yoni vyapad.
Design: This was a pilot study that included twenty female patients of Kaphaja yonivyapad (non specific vaginitis) from the Dept. of Prasooti tantra and Stree roga OPD of Rajiv Gandhi educational society’s Ayurvedic Medical College, Ron. Patients were administered Pippalyadi taila yonipichu for 7 days and were assessed before and after the treatment and followed up on the 14th day.
Results: This pilot study showed statistically significant changes in reduction of Katishoola (p<0.001), Kandu (p<0.001), consistency of the srava (p<0.001) and Srava pramana (quantity of the discharge) (p<0.001) showing the effectiveness of Pippalyadi taila yoni Pichu in the management of Kaphaja yonivyapad.
Conclusions: Pippalyadi taila yonipichu showed significant changes in the management of Kaphaja yoni Vyapad with the reduction of Katishoola, Kandu, consistency of the Srava and Srava pramana after the treatment
Some Bianchi Type III String Cosmological Models with Bulk Viscosity
We investigate the integrability of cosmic strings in Bianchi III space-time
in presence of a bulk viscous fluid by applying a new technique. The behaviour
of the model is reduced to the solution of a single second order nonlinear
differential equation. We show that this equation admits an infinite family of
solutions. Some physical consequences from these results are also discussed.Comment: 12 pages, no figure. To appear in Int. J. Theor. Phy
